EYEGLASS-MOUNTING.

To all whom it may concern:

Be it known that I, WATSON D. FENNI- MORE, residing in the city andcounty of San Francisco, State of California, have invented certain newand useful Improvements in Eyeglass-Mountings; and I do hereby declarethe following to be a full, clear, and exact description of the saidinvention, such as will enable others skilled in the art to which itmost nearly appertains to make, use, and practice the same.

This invention relates to improvements 111 eyeglass mountings, and moreparticularly ties in the face of the wearer; whereby the.

centers of the lenses, may be mounted to coincide with the exactpupilary centers of the respective eyes of the wearer, irrespectii e ofdifferences of distance, that may exist between either eye center andthe center of the nose. 7

Another object is to provide a mounting having an integral bridge bar,extending from strap to strap of the respective lenses.

Other objects and advantages will appear as the description progresses.

The invention possesses other advantageous features, that with theforegoing will forth at length in the following description, wherein Ishall outline in full, that form of the invention selected forillustration in the drawings accompanying and forming part of thepresent specification;

The novelty of the invention will be in cluded in the claims succeedingsaid specification. From this it is apparent that I do not restrictmyself, to the showing made by said drawings and specification, as I mayadoptmany variations within the spirit of Specification of LettersPatent.

bars with unequal studs on either end. The

long stud can be made up for either the right or left side, by selectionbefore the Patented Dec. 15, 1914.

Application filed July 31, 1918. Serial No. 782,353. r

bridge bar is finally shaped. Fig. 5 is a plan view from above of thebridge bar, showing the unequal studs, offset to bring the lenses closeto the eye of the wearer. One studbeing offset more than the other.

Fig. 6 is a similar view of the same, except that one stud is offsetforward, and the other backward; illustrating the adaptability of thebridge bar, to meet unusual demands withoutdeparting from the spirit ofthis invention.

The finger piece eyeglass mounting comprises the bridge bar 1, havingthe lens straps 2-2, soldered or otherwise attached to the studs 8-4, ofunequal length, on

either the right or'left side of the bridge bar. The nose guards 5-5,are pivoted on the -post screws 66, screwed into the swaged. bosses 7-7of the bridge bar. The necessary. frictional tension of the guardsagainst the nose of the wearer, is accomplished by the coil springs 8--8encircling these; posts, and expanding against the guards and-the bridgebar. The tension of these springs is overcome by the finger pieces 9-9,forming part of the guards, and extending forward of the mounting,within reach of the wearer; for placing and removing the eyeglasses.

An eyeglass mounting must be compact, rigid, strong and inconspicuous;yet easily -manipulated and formed to fit the idiosyncrasies in thefacial anatomy of the wearer. It is very rare, that an individual willhave eyes spaced equidistant, on each side of the center lineof thenose, which is the base or center from which mountings are calculated.

The term rigid means without spring and incapable of bending or beingadjusted without the use of tools and the exertion of considerableforce; beyond that which the handling of the eye glass without toolswould stand.

In the earlier forms of mountings, wherein the assemblage was made up ofa spring bridge, having lens straps with studs screwed to the bridge,straps with unequal studs could readily be incorporated in thecombination. In the present form of finger piece mounting, this latitudeof adjustment is not permissible within the limitations above set forth.The studs are too small to allow for any satisfactory adjustability inlength, without unsightly'enlargement. The strain on the mounting, inhandling the eyeglasses by the finger pieces, demands a strong rigidstructure, precluding any nega- 'tively built up, or screwed togetherbridge bar between the lenses.

In the present invention, particular novelty resides in the homogeneousbridge bar, having studs of unequal length, integrally combined with'thelens straps. Integrally, in the present sense including fusing,soldering, or otherwise permanently attaching the straps to the bridgebar, to form an inincluding a rigid bridge bar, having rigid,

tion, what is claimed and desired to secure by Letters Patent is 1. Afinger piece mounting for eye glasses integral studs of unequal length.

2, A finger piece mounting for eye glass s,

including a curved. bridge bar, having straight, integral studs ofunequal length.

3. A bridge bar for eye glass mountings having integral embossments, atequal distances. from the center thereof; and integral end studs ofunequal length.

l. A bridge bar for eye glass mounting s, .4

having integral embossments at equal distances from the center thereof;and integral end studs of unequal length and olf-set from the plane ofsaid bridge ban.

5. A bridge bar for eye glass mountings, having integral embossments atequal distances from the center thereof; and integral end studs ofi-setfrom the plane of said bridge bar. I

6. A. rigid bridgebar for-eye glass mountings, having integralembossments at equal distances from the center thereof; and integral,rigid end studs of unequal length.

7. A finger piece mounting for eye glasses, including a curved rigidbridge bar; integral embossments on said bridge bar equal distances fromthe center thereof; and integral end studs of unequal length, extendingin a. straight line from said embossments to' the lens straps of saidmountings.

In testimony whereof, l have hereunto set my hand this 25th day of July1913.
